2006 sighting

At approx 1920 on 8 Sep 2006, myself and 9 friends and family were preparing to go to a high school football game, we were all out front of my home when my wife asked me what some object in the sky was coming from across the tree line on the other side of our street, the object was black and round with a white light, not blinking on the bottom, it also had what seemed like a very dull white light spinning around it at its center, the object had no wings no visible engines, and made no noise, it appeared to be approx ½ the size of an airliner, it made absolutely no noise, and moved very slow, we watched it for about 5 minutes before our sons friend went and got his video cam corder and filmed it for about 2.5 minutes, my neighbors from across the street came out an witnessed it for about the final 5 minutes. The object after about 3 minutes changed the white light to a rapidly bright flashing red light for several seconds then would go to no lights at all before the white light on the bottom re-appeared. The object eventually continued due north till it was obscured by the trees.
